Add about 2 Tbsp of olive oil to a pot and let it get nice and hot. Add about 1/2 stick of butter to the olive oil and let it melt down into sizzling goodness. Saute the garlic, shallots, and fine onion until they are clear and tender - make sure too keep them moving so you don't burn anything. If there is even so much as a dark spot on one piece of garlic, it'll mess up the flavor of this sauce. Whisk in about 2 to 3 Tbsp on Chicken base (depending on the strength of the base). Mix in about 1/4 to 1/3 cup of flour to create a nice roux. Cook the roux for about 2 minutes and slowly add in about 3/4 bottle of wine while stirring rapidly and constantly. If you can't do this in one step, add a small bit of wine first and mix it until a smooth paste is formed, then add some more wine and mix until all lumps are out, and repeat. Your goal is to get a nice smooth liquid about the consistency of heavy cream.
